' MACHINE FOR CRE ASING COVERS FOR BOOKS, MAGAZINES, PAMPHLETS, AND THE LIKE.

Application filed April 2, 1906, Serial No. 309,291. Renewed July 6, 1908.

To all whom it may concern:

Be it known that 1, JOHN DAHLY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Creasing Covers for Books, Magazines, Pamphlets, and the Like, of which the following is a full, clear, and exact specification.

This invention relates to improvements in machines for creasing covers for books, and the like, whereby the cover may be rendered more flexible adjacent the binding.

A further object is to provide an improved machine of this character for crim ing or creasing the cover for a book or the ike, at the points where the cover is bent to form the back, and also along a line some distance from the back, whereby the cover may be opened on a hinge formed remote from the binding, thereby greatly increasing the life of the cover and avoiding the danger of detaching the cover by the opening of the book.

In the application for Letters-Patent filed February 5, 1906, Serial No. 299,574, there is shown and described an improved machine for crimping book leaves, and to con-- struct an improved attachment which may be applied to this machine, whereby the same may be readily and quickly converted from a leaf crimping, to a cover crimping machine, without detaching the parts, is another object of this invention.

A further object is to construct an improved machine of this character which will be simple in construction, cheap to manufacture, and efficient in operation.

To the attainment of these ends and the accomplishment of other new and useful objects, as will appear, the invention consists in the features of novelty in the construction, combination and arrangement of the several parts hereinafter more fully described and claimed, and shown in the accompanying drawing illustrating an exemplification of this invention, and in which Figure 1 is a front elevation of a machine constructed in accordance with the principles of this invention Fig. 2 is a front elevation of the machine with the cover creasing or crimping mechanism placed out of operative position. Fig. 3 is a plan view of a portion of a cover creased or crimped by this improved machine. Fig. 4 is a sectional view of a portion of a book having a creased Specification of Letters Patent.

cover applied thereto. Fig. 5 is an enlarged detail transverse sectional view of a portion of a cover showing the manner and shape of the crimps or creases formed by this machine. Fig. 6 is a detail view, showing a modified arrangement of the creasing or crimping rollers.

Referring more particularly to the drawing, and in which the same reference characters designate similar arts in the several views, the numeral 10 cesignates standards or supports having suitable journal boxes 1112 adjustahly mounted therein.

A shaft 13 is journaled in the boxes 11 and secured to this shaft and adjacent one end thereof is a corrugated sleeve or roll 14, which is held in place by any suitable means. Secured also to the shaft 13 is a roller 15, one end of which is adjacent the end of the sleeve or roller 14, and said roller 15 is of any desired length, preferably of a length to extend substantially half way between the standards 10. A roller 16 is also secured to the shaft 13 and is held against the end of the roller 15 in any suitable manner, preferably by means of a screw 17. This roller 16 is of a diameter equal to the diameter of the roller 15, and is provided with two peripheral grooves 18 spaced from each other, to form a bearing surface 19 between the grooves 18. An additional roller 20 is also mounted on the shaft 13, and is adjustably held in position in any suitable manner, such as by means of a screw 21. This roller 20 is of a diameter equal to the diameter of the roller 16, and is provided With a single peripheral groove 22. The grooves 18 and 22 in these rollers may be of any desired shape, but they are preferably V-shaped with the walls thereof disposed at an angle of 90. with and suitably spaced from the shaft 13, is journaled in the boxes 12. A corrugated sleeve or roll 24, mounted upon the shaft 23, is adj ustably held in position in any suitable manner, such as by means of a sleeve 25, whereby the roll or sleeve 24 may be adjusted longitudinally with relation to the companion sleeve or roll 14, with which it meshes and cooperates.

A plurality of feed rollers 26, adjustably mounted upon the shaft 23, are held in position in any suitable manner, such as by means of screws 27, and said rollers are preferably provided with rubber faces or peripheral ruber rings 28. These rollers are of such a di- A second shaft 23 parallel .(Fig. 5).

ameter that when in proximity t0, Wi1l be,ar noon the periphery of the roll Mounted also on the shaft 23,preferably between'the ond creasing roller 32 is adjustably secured to the shaft 23 by any suitable means, such as a screw 33, and said roller is provided with a single peripheral rib or web 34 which is adapted to project into and cooperate with the groove 22 in the roller 20. The sides of the ribs or webs 31-34 may be disposed at any suitable angle, but preferably at the same angle as the angle of inclination of the grooves 1822. The body portions of the rollers 29-32 are adapted to cooperate with the body portions of the rollers 16-20 to form additional feeding means for the material to be creased, as in Fig. 1. These creasings or crimping rollers may be constructed of any suitable material, preferably annealed tool steel.

Secured to one of the shafts 1320, and preferably on the outside of one of the supports or standards, is a driving pulley 35, and secured to both of the said shafts are gears 36 which mesh with each other, and by means of which both of these shafts are rotated in unison when the pulley 35 is driven.

- for guiding the paper through the roller.

With the parts assembled as shown in Fig. 1, the machine is ready to crease or crimp the material for the cover, and the material 38 is passed from the table 45 between the rollers, being guided therethrough by any suitable guides 46; the shafts 1.323 being adjusted to accommodate the material 38 of the desired thickness. During its passage between the rollers, the peripheral webs or ribs 3134 of the rollers 2932 will force the material adjacent thereto into the grooves 13'22 of the rollers 1620, thereby crimping or creasing the same, as at 394041 The ribs 31, as well as the grooves 18, are permanent, respectively, with relation to each other, whereby the width of the space 42 formed between the grooves or creases 3940 is constant, but the rollers 20 and 32 are adjustable with relation to the rollers 16 and 29, by means of which the space 43 formed between the grooves or creases 40 and 41may be varied according to the thick- .ness tor the number of signatures comprising the book to which the cover is to be applied.

The .covenmay be applied in any-suitable manner. The signatures 44 are assembled and secured in any manner, and then placed upon the inside of one leaf of the cover with their'rearedge adjacent either of the grooves '39 or 40, according to the process of assembling. Glue is then applied to the edge, and the adjacent portion of the top of the signatures and to the space 42 Land 43, if desired. The cover is then folded upon :the crease or crimp 39 or 40, so as to cause the portions 42 and 43 to be secured in position. With this arrangement it will be seen that when the book is completed the cover .33 will open upon the crease or crimp 41, at a point remote from the binding, as shown in Fig. 4, 1

thereby transferring the strain from that point and obviating the danger of detaching the cover when the book is opened, and by being creased, the surface of the material is not cracked or out, which will greatly prc long the life of the material and the cover. When used for crimping or creasing covers, the material will not come in contact with the corrugated rollers 14 and 24, as it is guided from the end of the machine remote from the rollers 14 and 24, and is not of sufficient width to extend thereto.

When it is desired to use the machine for the purpose of crimping ledger sheets, similar to the previous application now on file, it is necessary to throw the rollers 162029 32 out of operation. This is accomplished by first loosening the screws 213033 respectively of the rollers 202 932. The shaft 23 is then-raised slightly, which is permitted by loosening the adjusting screws 37, so that the ribs or webs on the rollers may be removed from their cooperating grooves, afterwhich the rollers may be moved to the desired position. The roller 20 is moved to a position directly in line with and is engaged by one of the feed rollers 26, which is preferably located adjacent one end'of the shaft 23,

and is secured in position, while the rollers 7 2932 are secured to the shaft 23 at a position intermediate the rollers 1620, where they will be out of contact with acooperating roller, the roller 16 remaining stationary. Nith this arrangement and with the parts assembled and adjusted as shown in Fig. 2, the ledger sheets may be fed and crimped in a manner set forth in the pending application, the rollers 26 and 20 cooperating toassist infeeding the leaves through the corrugated rollers 1424. Thus it will be seen that a machine thus constructed and ar-' ranged'may be readily and quickly converted from one style of machine to another, without detaching or removing any of the parts. In this exemplification of theinvention there is shown and described a construction of machine comprising one pair of cooperating rollers provided with spaced ribs for producing two grooves, one at each corner of the back, and an additional pair of coo erating creasing rollers for producing a sing e crease in the top of the cover remote from the binding; but it may be desirable to roduce a similar crease or groove in the bac and it is therefore obvious that the desired result may be accomplished by the addition of another set of creasing rollers.

It may sometimes be desired to apply a cover to small pamphlets where there is only one, or a small number of signatures, in which instance there would be no necessity for the parallel creases for the back or thickness of the book, and only a single central crease would be necessary. In order to accomplish this and produce the single crease or groove, a modified arrangement of the creasing or crimping rollers would be necessary, as shown in Fig. 6. In this arrangement the rollers 2032, having the single cooperating rib and groove would be placed adjacent the roller 15, and the rollers 1619 having the spaced cooperating ribs and grooves would both be adjustable, out of operative position. That is, the position of the pairs of creasing rollers would be reversed from the position shown in Figs. 1 and 2.

It is to be understood that it is not desired to be limited to the exact details of construction, or the arrangement of the several parts, as numerous changes may be made therein without departing from the spirit of the invention.

IVhat is claimed as new is:

1. In a machine for creasing covers and the like, the combination of a pair of cooperating creasing rolls between which a sheet of material is adapted to pass, one roller having spaced peripheral grooves, spaced peripheral ribs on the other roller projecting into the grooves and adapted to produce a constant space between the creases formed thereby in the material, a second pair of cooperating rolls, one of said rollers having a peri heral groove and the other being provided with a cooperating rib for producing a single groove in the material, means whereby the position of the single groove produced by the second set of rollers may be varied with relation to one of the first said grooves, feed rollers, means for adjusting the rollers of one set into an inoperative position, one of the rollers of the inoperative set being adapted to cooperate with one of the feed rollers for feeding the paper into the active set, and means for rotating the rollers.

2. In a machine for creasing covers and the like, the combination of a pair of cooperative creasing rolls between which a sheet of material is adapted to pass, one roller havin spaced peripheral grooves, spaced periphera ribs on the other roller projecting into the grooves and adapted to produce a constant space between the creases formed thereby in the material, a second pair of cooperating rolls, one of said rollers having a ieripheral groove and the other being provi ed with a cooperative rib for producing a single groove in the material, means whereby the position of the single groove produced by the second set of rollers may be varied with relation to one of the first said grooves, feed rollers, an adjustable gage for the paper, means for adjusting the rollers of one set into an inoperative position, one of the rollers of the inoperative set being adapted to cooperate with one of the feed rollers for feeding the paper into the active set, and means for rotating the rollers.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 29th day of March A. D. 1906.
